The Quran

ما كانَ لِبَشَرٍ أَن يُؤتِيَهُ اللَّهُ الكِتابَ وَالحُكمَ وَالنُّبُوَّةَ ثُمَّ يَقولَ لِلنّاسِ كونوا عِبادًا لي مِن دونِ اللَّهِ وَلٰكِن كونوا رَبّانِيّينَ بِما كُنتُم تُعَلِّمونَ الكِتابَ وَبِما كُنتُم تَدرُسونَ

(Saheeh International)

It is not for a human [prophet]¹ that Allāh should give him the Scripture² and authority and prophethood and then he would say to the people, "Be servants to me rather than Allāh," but [instead, he would say], "Be pious scholars of the Lord because of what you have taught of the Scripture and because of what you have studied."

Or any believer.
Or in the case of Prophet Muḥammad (ṣ), "the Book" (i.e., the Qur’ān).
